To meet the practical demands of mobile Ad Hoc network on quality of service, we proposed an improved wireless on-demand routing protocol on the basis of traditional AODV. We integrate multi-path routing into route discovery process and arrange data originated from source to be transmitted over several different paths concurrently, and defined the path level to evaluate the path’s transmission ability based on its available bandwidth. Numerical simulation results demonstrate the proposed routing protocol outperforms AODV in end-to-end delay, packet delivery rate and network lifetime.
